Application lled August 31, 1915. Serial No. 118,284.

To all Iwhom it 'may concern.'

Be it known that I, ISRAEL MILLER, a citizen of the United States, residing at Pawtucket, in the county of Providence and State ot' Rhode Island, have invented new and useful Improvements in Shock-Absorbers, of which the following is a specification.

The present invention relates to shock absorbers for vehicle springs.

In carrying out my invention it is my `pnrpose to construct a shock absorber which may be easily and quickly applied to the ends of a vehicle spring and which is in the nature of an arched member or link confstrncted of spring material having arranged upon the inner face thereof oppositely disposed shoes and arranged between the said shoes -is a helical spring exerting a tension between the opposite'ends of the link and adapted when thevehicle springs are subjected to an undue strain to assist in resisting the strain by partially absorbing the same, so as to prevent any violent shock or jar incident to the vehicle traveling over uneven surfaces or from other causes.

Another object of the invention is to provide a shock absorber which shall be extremely simple and cheap and which may be easily and readily attached to or detached from the ends of an ordinary vehicle spring. lVith the above and other objects in View, the improvement resides in the construction, combination and arrangement of parts set forth in the following specification and falling within the scope or' the appended claims.

In the drawing: Figure l is an end View of the )vehicle spring showing my improvement "attached thereto, Fig. 2 is a s1milar view showing the improvement arranged between the end links of the spring, Fig. 3 is a central longitudinal sectional View through the same, and Fig. 4 is a perspective Viewof the improvement detached.

My improvement contemplates the employment of a round link, l, the same being constructed of some heavy suitable resilient material and having its ends spread and bifurcated, and the end arms 3 provided by the said bifurcations 'having eyes provided with openings 4 through which are passed bolts 5 that secure the ends of the link to the end leaves 6 and 7 of a vehicle spring, the inner wall of the link is preferably provided with a circumferential slot or depression 8 which is adapted to contact with the sides of shoes 9 and l0. respectively, the said shoes being preferably disposed diametrically opposite each other adjacent the open end of the link. The shoes are sustained in proper position through the medium of an adjust able securing element in the nature of a screw bolt 10, and the inner faces of the links are provided with lugs or bosses ll which Surround the end convolutions of a helical spring 12. The link may be arranged either outwardly or inwardly of the ends of the spring, as illustrated in Figs. l and 2 of thedrawings and by an arrangement as just described it will be noted that` thc re` silient link and spring 1Q will effectively absorb any shock to which the vehicle springs are subjected.

F rom the above description, taken in connection with the accompanying drawing, the simplicity of the device, as well as the advantages thereot` will, it is thought, be perfectly apparent to those skilled in the art to which such invention appertains without further detailed description.

Having thus described the invention, what I claim is:

1. A shock absorber, comprising a round spring link having spaced ends provided with ears which are secured to the ends of a vehicle spring, diametrically opposite shoes upon the inner tace of the link, means :for sustaining the shoes in the link, lugs formed with the inner faces of the shoes, and a. helical spring surrounding the lugs and contacting with the shoes.

2. In a shock absorber, a round spring side walls of th(` 011111111111. screw 111e111b01s for 5LC111'111g1t11vblucks11111111tl1cl111k,s111 lhlucks Vhaving" their 11111111' 121005 provided wit-11 lugs.
